CryoSpheres Insulation Panels

CryoSpheres™ insulation, which consists of hollow glass bubbles, combines in a single material the desirable properties that other insulations only have individually. CIP provides efficient storage and transfer of cryogens and cryogenic propellants in space and terrestrial environments. CIP consists of vacuum-tight Cryosphere™-filled panels configured to any shape and are ideal for field and retrofit installations. CIP is lightweight, significantly outperforms foams, is less maintenance intensive and costs less compared to MLI, is easily applied, withstands unlimited thermal cycles, and can accommodate complex geometries and shapes.

Some of TAI Inc.'s staff previously worked on the later stages of development and marketing of CryoSpheres™ insulation and CIP's as a commercial product, and TechApps has a patent on the use of CryoSpheres™ in insulated panels. 

The primary components of the CIP have been optimized to balance excellent thermal performance with low cost. Panel materials have been chosen with an emphasis on proven application at cryogenic temperatures and vacuum conditions, common availability, and established fabrication practices. The versatility of CIP permits the design configuration to be optimized for the specific application, therefore allowing variation in the design parameters in order to achieve explicit project objectives.

Applications (but not limited to):

  • Space vehicles.    
  • Aircraft.    
  • Donor organ transport containers.    
  • Scientific freezers & ovens.    
  • Cryogen systems.

Cryogen transfer & vent lines for:

  • Air separation units.
  • Cold boxes.
  • Cryogen storage tanks.
  • Cryogen ship tankers.
  • Cryogen truck trailers.

CryoSpheres™ insulation panels combine ruggedness, low mass, ease of application (including field installation), good thermal performance, low life-cycle cost, little to no maintenance, and can be configured to accomodate complex shapes and geometries. The current technologies are either expensive (evacuated multi-layer insulation) or degrade quickly (polyurethane foam). Both are maintenance intensive to retain the original performance level. In the case of MLI, CIP require far less costly monitoring, vacuum maintenance and installation costs. Polyurethane foam insulation degrades starting with the first thermal cycle when the adhesive interface between the pipe and foam inner surface separate, allowing collection of moisture therefor requiring replacement after only 3 years of use.
